LAWRENCE, Kansas (Ticker) -- Wayne Simien and Raef LaFrentz provided the inspiration, while Nick Collison and Kirk Hinrich supplied the points.
On the day Simien returned from a lengthy absence and former Jayhawk LaFrentz was honored, Collison and Hinrich scored 19 points apiece to lead 10th-ranked Kansas to a 70-51 Big 12 Conference victory over Iowa State.
Simien missed 11 games with a dislocated right shoulder but contributed seven points and seven rebounds in 18 minutes off the bench. He was averaging 15.9 points and 8.7 rebounds before being sidelined.
"I was really pleased to get Wayne back in and get him some minutes," coach Roy Williams said. "I told him, we aren't taking baby steps, but we are taking just steps to get him back into the flow.
"For Wayne, I thought 18 minutes was fine. We'll probably try to increase his work load a little bit but monitor it as we go along. He is not the Wayne Simien who stopped playing at Kemper Arena, for sure."
LaFrentz, playing his fourth year in the NBA with the Dallas Mavericks, returned to Allen Fieldhouse to see his jersey raised to the rafters.
He also saw fellow Iowa natives Collison and Hinrich play against their home state team for the last time and help Kansas (19-5, 9-1 Big 12) win its 16th straight conference home game.
In addition to the festivities surrounding LaFrentz, over 150 former Kansas players, coaches and managers were honored at halftime as the Jayhawks celebrate their 105th season of basketball.
"It was a weird day," Williams said. "There were just so many things going on. It was almost a dysfunctional start to a game and that is how the whole game was played as well. It was a (messed) up day, but it was a `W' and we were able to honor some people. I think our players now have a better appreciation of Kansas basketball and history, and it was fun for me to see all those guys."
Collison grabbed 11 rebounds and Aaron Miles added 14 points, nine assists and a school-record nine steals as the Jayhawks extended their overall winning streak to six games.
Kansas has won 24 of its last 25 regular-season Big 12 games and took sole possession of first place in the conference.
"This is where we want to be right now," said Collison, who has scored in double figures in 26 of 27 games dating to last season and passed Marcus Fizer for second place on the Big 12's all-time scoring chart. "We still have a lot of tough games at the end of our schedule. We realize that. We just have to go out and play every single night."
Jake Sullivan scored 18 points and Jared Homan had 10 and 10 rebounds for Iowa State (12-9, 2-8), which is winless in five Big 12 road games and is 8-39 at Kansas.
"Kansas did a good job of some stuff defensively, but we are pleased with how we played today," Sullivan said. "If we could have executed better and cut down on the turnovers, it's a ballgame. We think that we can win these last six and that is all we're concentrating on."
Cyclones coach Larry Eustachy was ejected with 12:08 left in the second half of a game that featured four technical fouls. Arguing a call against Iowa State center Jackson Vroman, Eustachy drew two technical fouls.
"I am a little bit confused because I thought they called Jackson's fifth foul," Eustachy said. "I saw his fifth foul, so I walked out on the court thinking it was his fifth foul and I had to sub somebody. At the same time, I am pleading my case and then I had a technical out of left field and it all went from there."
One minute later, Vroman shoved Simien under the Kansas basket. Homan stepped into the fray to block Simien from charging Vroman, but he was hit in the back of the head by Miles.
Vroman was given a shoving foul and technical, which put him over the limit and out of the game, while Miles received a technical. By that time, the Jayhawks had the game well in hand.
"We made a deal as a team that we are going to fight," Sullivan said. "(Eustachy) didn't agree with the way the game was being called and he voiced his opinion and he went down fighting for us. If it hurt us or if it didn't, who cares. We went down fighting today. We all could have done more today and could have made different decisions."
Simien entered the game with 17:27 left in the first half to a standing ovation. The sophomore forward was cheered again a little more than a minute later when he hit a jumper to give the Jayhawks a 7-1 advantage.
"He is going to help us out," Collison said. "He is going to get better every time out there. He still isn't practicing at full intensity yet, but I think when he gets back in that form, he will help us out a lot more. He made a couple of shots and looked good."
"You can tell he is favoring his shoulder a little bit, but he is looking good," Kansas forward Jeff Graves added. "He really gave the team a burst. I think we can go pretty far with everybody in the game and healthy again."
Collison had 12 points and eight rebounds in a lackluster first half that ended with Kansas leading, 28-22.
The Jayhawks started the second half with an 8-2 spurt, capped by a 3-pointer from Hinrich, to go ahead 36-24 with 15:22 left.
Iowa State twice pulled within eight points, the last time on a basket by Homan with 13:32 remaining, but Kansas responded with a 22-8 run to take a 60-38 bulge with 6:40 left. The Cyclones never threatened the last half of the period.
Kansas shot 40 percent (10-of-25) in the first half but righted itself in the second with a 54-percent mark (15-of-28). The Jayhawks scored 25 points off Iowa State's 18 turnovers but converted just 17-of-33 free throws.
"We missed some shots early in the game," Williams said. "We missed a horrible number of free throws. It was a very ugly type of game. Maybe noon on a Sunday morning is too early and (the players) may not like to play at that time. I told them all, whatever they did last night, change it before we play again."
The Cyclones were held to 38 percent (19-of-50) shooting and were outrebounded, 38-30.
